                     CVE-2026-56136
    Debian Bug     : 1142144

    Several vulnerabilities were discovered in NTFS-3G, a read-write NTFS
    driver for FUSE. A local user can take advantage of these flaws for
    local root privilege escalation.

    For the stable distribution (trixie), these problems have been fixed in
    version 1:2022.10.3-5+deb13u2.

    We recommend that you upgrade your ntfs-3g packages.

    For the detailed security status of ntfs-3g please refer to its security
    tracker page at:
    https://security-tracker.debian.org/tracker/ntfs-3g

    Further information about Debian Security Advisories, how to apply
    these updates to your system and frequently asked questions can be
